我国南方松外生菌根资源调查

调查研究了我国南方松不同森林类型外生菌根菌资源、种类及其生态分布，分析了菌根共生体之间的关系及环境因子对菌根真菌分布的影响，提出了与南方松形成外生菌根的真菌１１５种，隶属１４科，３０属；提示了树种、植被了菌根真菌分布及其菌根形态的关系；菌根真菌的分布随温度，湿度，地理环境及土壤条件变化的规律。从而得出第一代南方松林下外生菌根真菌发生演替及彩色豆马勃是其最重要的先锋菌根真菌的结论；进一步论证了南方松

FLORISTIC SURVEY OF ECTOMYCORRHIZAL FUNGI FOR THE SOUTHERN PINE IN CHINA

This Paper investigates the resources, species composition and ecological distribution of ectomycorrhizal fungi in different types of pine stands, and analyzes the relstionship between the ectomycorrhizal symbionts and environmental effects on the fungus distribution. The results show that 115species belonging to 14 families, 30 genera are found to be associated with southern pine in China.The relationship between the woody species and the ectomycorrhizal fungi, the external appearanceand internal structure of the mycorrhisae and the rule that fungus distribution varies with temperature,moisture. geographiCal environment and soil conditions are revealed. Therefore, it can be concludedthat there is an orderly succesion, in which Pisolithus is the most important early-stage fungusin pine forests of the first generation in Southern China. Based on the conclusion, the necessity for theapplication of ectomycorrhizae in the management of Pines in Southern China and the selection principles of superior fungi for the establishment of first-generation Pine stands are further discuss and confirmed.
